ELECTRIC SWITCH Filed June 4. 1926 Patented Jan. 21, 1930 UNITED STATES PATENT OFFICE TO THE ARROW-HART & HEGEMAN ELECTRIC COMPANY, F HARTFORD, CONNECTI- CUT,'A CORPORATION OF CONNECTICUT ELECTRIC SWITCH Application led June 4,

One object of my invention is to, construct an electric switch o f a number of laminations of insulating material, and in which the metallic terminals are held in position between certain laminations, as fully described hereinafter.

A .further object of my inventionis to` make a comparatively small switch, and to dispense with the use of screws which usually attach the terminals to the body of the switch structure.

In the accompanying drawing:

Fig. l is a perspective view of an electric switch embodying my invention;

Fig. 2 is a plan view, with the casing removed, illustrating the body of the switch structure;

Fig. 3 is a sectional view on the line 3-3, Fig. 2;

Fig. 4 is a section on the line 4 4, Fig. 2, with a terminal removed;

Fig. 5 is a sectional view on the same line as Fig. 4 but with the terminal in place;

Fig. 6 is a sectional view on the line 6-6, 25 Fig. 5;

Fig. 7 is a perspective view illustrating the several laminations 0f the body portion of the switch;

Fig. 8 is a detached perspective View of s0 one of the terminals; and

Figs. 9 and 10 are plan views partly in section illustrating modifica-tions of the invention.

o1 is the body of the switch, made of a number of laminations of insulating material, as clearly shown in Fig. 7. These laminations, with the exception of the end sections 3, are recessed to form a cavity 4 for the reception of the switch contact members, which are shifted from one position to another by turning the handle 5, Fig. 1. This handle is pivotally mounted on a cross-bar 6 located in a portion 7 of the casing 8.

The casing 8 extendsv over the switch body 1 and down on each sidethereof, as clearly shown in Fig. 1. The portion 7 of this casing is threaded for the reception of a nut for --se`curing the switch onto a panel-board or other support. The lamuatons are held together by pins `192e. seria1 No. 113,770.

9, which extend through the several sections as shown in the drawing, and rivets 10 secure the casing to the body portion, the rivets ,i

extending through the lower portions of the laminations in the present instance.. The means for fastening the casing to the body portion may be modified without departing from the essential features of the invention.

The laminations 10a, 11, 12 and 13 differ in form. The section 10a has a recess of th'e same width as the other sections, but the bottom portion 14 is raised as in Fig. 4, so as to form a slight partition, dividing the two sections of the body portion. This partition also acts as a guide for the movable switch members.

The section 13 has a recess at one side as shown at 15, to accommodate the terminal 16, Fig. `8. When in position as shown in Fig. 5, the terminal 16 extends above the bottom of the recess 4, and is in position for the pivoted switch member to contact therewith. The eye portion 17 of the terminal 16 is in the circular portion of the recess, the wire being passed through the eye portion and the metal of the eye clamped onto the wire as shown in Fig. 5.

The sections 12 are notched at 18, and the sections are located at eitherl side of the section 13, so as to allow space for the wire and to allow the wire of the terminals to pass out at the end of the switch, as clearly shown in Fig. 6. This construction is duplicated on the other side of the partition 10a,

When the parts lare assembled, thevpins 10 are 'inserted and riveted, so as to secure the several sections together with the terminals 16 in proper-position, after which the casing 8 is located on the body portion and secured thereto by the .rivets 10.

In some instances, instead of forming the recesses 17 in the sections 12, the wires may extend to either side of the body portion as shown in Fig. 9 and bound together by a sleeve 20, or the terminal 16 may be connected to metallicypins 19 extending through openings in the body portion and coupled to the terminals. The wires leading from' the switch are connected by, and passed through By the above arrangement, the terminals 16 are clamped in position in the body portion by the several insulating sections of the body portion. No screws are necessary to secure the terminals in position, and the terminals 'may be connected to the wires leading to the switch in any suitable manner.

A switch of this designcan be made very i small and compact, and is especially applicable as a. radio switch, but it will be understood that the invention can be applied to other switches withoutdeparting from the scope of the constructions herein set forth.v

2. The combination in an electric switch, of a body portion made up of a series of laminations, certain of the laminations being cut away to orm a cavity for the reception of a movable switch element, and certain of said lamlnations having recesses communi- -cating with said cavity; and metallic terminals mounted in said recesses and being exposed in said cavity, the laminations adjoining the recessed laminations being notched so as to form open spaces on' one side of the terminals for the accommodation of conductors leading fromthe terminals.

3. The combination in an electric switch,

of a body comprising a series of laminations of non-conducting material placed side by being exposed in the cavitythe laminations at the side of the contact-housing lamination being Y notched to accommodate conductors leading from the several terminals.

. 5. A switch structure having a body portion made of a series of laminations secured side by side, the outermost laminations being solid and the inner laminations being recessed to `form a cavity; xed terminals mounted in the body portion intermediate the sides thereof and having their contact ends exposed in the cavity; a casing secured to the body portion; and a movable contact member mounted in the casing and extending into said cavity and arranged to come into contact with said fixed terminals.

6. In an electric switch, an insulating body formed of a plurality of parallel members,

a cavity formed in one or more of said mem bers, within which a movable switch member may operate, some of said members lying on the outside of said body and closing the sides of said cavity, switch contacts fitted into recesses in said body and maintained in said f recesses by means of said outer members of said body, said switch contact recesses ex-.

tending to the outside of said body.
